Abstract (en)

The device applies a digital control command, which can be evaluated by an internal controller, to the input of each IC (IC1-IC3), whose earth connection is connected to earth potential. Each IC outputs state information. The inputs (E1-E3) of several ICs are connected together and each output (A1-A3) is separately fed to a control unit (22). After receiving a blocking control command each IC locks the evaluation of received control commands and the output is set to a state in which control signals can be received and evaluated. The external control unit feeds a trigger control signal to a selected IC via its output, whereupon the controller removes the lock and control commands are output to set the operating parameters to the inputs of the ICs. Independent claims are also included for a method of setting operating parameters in several programmable ICs and for a programmable IC.

Abstract (de)

Die Erfindung betrifft eine Einrichtung zum Einstellen von Betriebsgrößen in mehreren programmierbaren integrierten Schaltungen (IC1, IC2, IC3). Die Eingänge (E1, E2, E3) mehrerer integrierter Schaltungen (IC1, IC2, IC3) sind miteinander verbunden, wobei jeder Ausgang (A1, A2, A3) getrennt zu einer externen Steuereinheit (22) geführt ist. Nach Erhalt eines Sperr-Steuerbefehls wird jede integrierte Schaltung (IC1, IC2, IC3) verriegelt. Die externe Steuereinheit (22) führt an eine ausgewählte integrierte Schaltung (IC1) über deren Ausgang (A1) ein Freigabe-Steuersignal zu, woraufhin die interne Steuerung (10) die Verriegelung aufhebt. Anschließend werden Steuerbefehle zum Einstellen der Betriebsgrößen an die Eingänge (E1, E2, E3) der integrierten Schaltungen (IC1, IC2, IC3) ausgegeben. <IMAGE>
